Almost all of us had immigrant ancestors, although not all of them chose to become American citizens. Necessary for voting and to attain some legal status, citizenship was not a priority for those who didn't expect to buy land, weren't welcomed by the often-crowded communities in which they found themselves, or didn't especially care about electing local or national officials. Prior to September 1906, naturalization was a function of individual states and could take place in any court in the country. The number of years one had to be a resident fluctuated over time, and there were no restrictions about where you had to complete the process once you started it. And it was a process. First, an immigrant had to file a declaration of intention to become a citizen; these were often called first papers. The next step, after a certain number of years had passed, was a petition for citizenship, or final papers.
